Throwing codes 171 and 172 02 sensor wire?

I just got done rebuilding my 5.3 out of the 2007 Trailblazer. Now I've got it all put back together and I've got codes 171 and 172 and that is all I have, I think its the cord to my 02 Sensor wire for bank one. Can it be anything else? I did notice that it looked like the wire got squished not the connector but just the wire itself that is on the harness not the sensor.
